I don't remember Bethesda games being demanding since Fallout 3, at least in my case. I've never had a high-end PC and I have always been happy with the performace. Sure, I can't have the advanced ENBs for Skyrim, not even now, but to be honest, the hw requirements are the least of my concern and although it's not gonna be the most beautiful game of the year, I don't think I will be needing that many graphical mods

BGS Games arent demanding usually, but it seems this one might be. So far no evidence of loading screens, around the same map size as skyrim but you can go in majority of the interiors and there are no major natural objects blocking your path (mountains) and the game looks freaking gorgeous. So right now it could be a safe bet to consider this game demanding ATM.Hopefully we see more soon

Aside from that, your listed system does not meet the minimum processor spec for even New Vegas. 1.8 GHz with a suggested min of 2.0 - that probably wouldn't exactly be a dealbreaker for NV, but it would guarantee an insanely slow and choppy experience.

What patrikfroman says is an overriding concern, but I figured I'd point that out too.
